A wireless device (e.g., an access point or wireless station) may transmit, at a start of a TxOP to one or more wireless devices, signaling indicating that the TxOP includes one or more sub-TxOPs. The wireless device may contend, during a first contention period (CP) preceding a first sub-TxOP of the one or more sub-TxOPs, for access to a medium. The wireless device may transmit, upon determining that the wireless device can transmit in the first sub-TxOP, data to at least one wireless device of the one or more wireless devices.

The non-AP MLD may transmit, to the AP MLD, one or more additional uplink frames that include the one or more respective new addresses.

Abstract: Embodiments are disclosed for privacy enhancement (PE) beacon frames. A PE station (STA) can receive a PE beacon frame comprising a media access control (MAC) header that includes a first random identifier (ID) and a first checksum ID, determine that configured beacon parameters are satisfied, and then receive the PE beacon frame. When the first random ID and the first checksum ID correspond to an affiliated PE access point (AP) of a PE AP multilink device (MLD), to identify the PE AP MLD the PE STA can determine a checksum value using a AP MLD ID of the PE AP MLD and the first random ID, and based on a comparison of the determined checksum value with the first checksum ID, identify the PE AP MLD. In some embodiments, a location of a change sequence number adjacent to the MAC header enables early termination of the PE beacon frame reception.
